a tie where parts subjeetedtothefgreatest wear may be easily andconveniently replaced, thus considerably reducing the cost ofmaintenance. I I

Other objects will become more apparent by referenceto thedrawings, thespecification and the claims forming partv thereof.

Apreferred form of the invention is illustrated in the accompanyingdrawings in Which Figure 1 is a perspective View of the tie with one ofthe rail bed blocks and clamping plates removed. Fig. 2 is a perspectiveview of the clamping plate. Fig. 3 is a perspective View of a rail bedblock. Fig. 4 illus trates a longitudinal sectional view of theassembled tie.

The tie comprises a side member 1 having at its ends flanges 2 extendingat right angles thereto and provided with a plurality of apertures. Asimilar side member 3 is arranged in staggered relation to the sidemember 1 whose one end projects beyond the corresponding end of itsaccompanying member while its other end stops short of the correspondingend of the other side member. The side members 1, 3 are formedintegrally with the flanges 5 extending at right angles thereto, but inopposite direction to the flanges 2 and 4, respectively. The flanges 5are in alinement when the side members occupy the working position. Between said side members an oblong rectangular filler block 6 of concreteis provided, whose length is equal to the length of the overlappingportion of the side members 1, 3. The flanges 5 are embedded in the concrete block 6, as is obvious from Fig. 1 of the drawings, whereby theside members are locked in position. The concrete block and thecontiguous portions of the side members *c onstitute -the"middle portionof the tie and-are of a form similar to the ordinary woodenties, but have greaterdurability. A block 7 offlbrous niateriahsuch"aswood, is

placed at each end contiguous tothe concrete block 6 and forms anextension thereof. The

block 7 contactson one 'sidewith' the projectlngend ofone of the sidemembers and is slightly thickerfjth'an thecon'crete block 6, as isobvious from Fig. a. These wooden blocks Tserve as supports for therails and are adapted to absorb shocks. It is understood that the wooden' blocks are treated by the *cre'o'sote process preparatory to "beingused as railbeds.

I *Inorder to hold the blocks in place'angle I platesfS areprovidedwhich "engage the bed blocks Tod-two sides andabut the flangeser "a djacent ends of'the side members. One leg of the 7 angle plateextends f parallel to, the

me'i'nber when the parts are assembled. The other leg of the angle plate8 is provided with a flange 9 adapted to abut the flange of the otherside member and is also provided with a plurality of apertures. Bolts 10or other suitable fastening means may be inserted in the registeringapertures, thus holding the parts of the tie securely together. A baseplate 11 is provided which approximately extends over the entire lengthof the tie structure.

From the foregoing it is evident that the middle portion of the tiestructure is practically indestructible and only the blocks constitutingthe rail bed are subject to wear. These blocks may be easily andconveniently replaced when worn out, as only a small portion of thepavement must be removed in order to permit the replacing of the bedblocks 7.

I am aware that slight modifications and changes may be made in thestructural form of the tie or in the arrangement of the parts and I wantto avail myself of all such departures which come within the scope of myinvention, as indicated in the appended claims.

I claim 1. A tie comprising a pair of side members each provided with aflange, an elongated block of wear resisting material arranged betweensaid side members, said flanges extending into said elongated blockflangeof'one side member and is provided w th a plurality of apertureswhich register with "the apertures in"'saidflange of'the'side shockabsorbing means adapted to form a bed for the rails provided adjacenteach end of said elongated block, and means for se" curely holding thesaid parts together.

2. A tie comprising a pair of side members arranged in staggeredrelation to each.

other, afiller block of concrete provided between said side members andextending between the overlapping portions of said side members, shockabsorbing means adapted to formfa bed for the rails provided adjacenteach end of said filler block and abutting the same, and means forsecurely holding the said parts together. 7

'3. A tie comprising apair of side members arranged in staggeredrelation to each other, a rectangular block of concrete provided betweensaid side members and having a} length equal to the length of theoverlapping portions of said side members, rail bed blocks composed offibrous material abutting the ends of said rectangular block and formingextensions thereof, and means for securely holding said parts together.

4. A tie comprising a pair of side members arranged in staggeredrelation to each other, a rectangular block of concrete provided betweensaid side members and having a length equal to the length of theoverlapping portions of said side members, rail Copies of this patentmay be obtained for vided between said side members, rail bed blockscomposed of fibrous material abutting the ends of said rectangular blockand forming extensions thereof,- and angle plates contacting with twosides of said rail bed blocks, said angle plates being secured toadjacent ends of saidside members.

6. A tie comprising a pair of side members arranged in staggeredrelation, a filler block of wear resisting material arranged betweensaid side members and extending throughout the overlapping portions ofsaid side members, rail bed blocks of fibrous ma terial formingextensions of said filler block and having a length equal to the lengthof p the projecting portion of said side members, v a.

means for interlocking said side members I rand said filler blocks andmeans for securely holding the said parts together.

In testimony whereof I hereunto .aflix my signature.
